Abstract: We discuss the main features of a phase-space noncommutative model of quantum mechanics and its applications for quantum cosmology and black holes in the context of the Kantowski-Sachs minisuperspace geometry.
Abstract: A new generation of radio telescopes with unprecedented capabilities for astronomy and fundamental physics will be in operation over the next few years. I will address some of the possibilities for Cosmology offered by this new generation of telescopes, such as ASKAP, MeerKAT, LOFAR and the future SKA.
Abstract: In this talk we discuss the quantum theory of a scalar field on LQC Bianchi I geometry. By focusing on single modes of the scalar field, we show that, evolution of the quantum field on the background quantum space-time leads to a classical effective geometry emerging whose components depend on the quantum geometrical operators.
Abstract: The Eddington-inspired Born-Infeld (EiBI) theory of gravity has many attractive features. In particular, it may lead to a non- singular description of the Universe and it may accommodate compact stars made of pressureless dust.
Abstract: Warm inflation provides an attractive solution to the so-called eta-problem that generically plagues supergravity and string theory models, with additional dissipation damping the inflaton's motion and simultaneously producing radiation during inflation.
Abstract: n-DBI gravity is a gravitational theory introduced in arXiv:1109.1468[hep-th], motivated by Dirac-Born-Infeld type conformal scalar theory and designed to yield non-eternal inflation spontaneously. I explain that any solution of Einstein gravity with a particular curvature property is a solution of n-DBI gravity.
